The 28-year-old has been unveiled by the Toffees to end a 12-year association with the Gunners.

After scoring 108 goals in 397 games, Walcott has paid tribute to the "incredible support" from the fans and admits he is "sad" to leave.

"I would like to say a big thank you to everyone involved Arsenal – manager, coaches, backroom staff, and all the many people at the club that have been part of my family for the past 12 years," Walcott said on Twitter.

"I would also like to thank all my team mates I have had the pleasure of playing alongside, but most importantly the fans for their incredible support.
